IMPROVEMENT IN APPARATUS FOR DRAINING SUGAR.

Specification forming part of Letters Patent No. Q91 h5, dated July l0,1860.'

To @ZZ whom it may concern:

Be it known that I, J. J. UNBnHnGnN, of Baton Bouge, in the parish o fEast Baton Bouge and State of Louisiana, have invented a new andImproved Apparatus for Draining- Sugar; and I do hereby declare that thefollowing is a full, clear, and exact description of the same, referencebeing had to the'accompanying drawings, forming a part of thisspecification, in which- Figure 1 represents a longitudinal verticalsection of my apparatus, showing the same in a position to receive thehot liquid sugar, in red outlines, and in a draining position in blackoutlines; Fig. 2, a horizontal section of the same when used forcooling; Fig. 3, a similar section of the same when used for draining.

Similar letters of reference in both views indicate corresponding parts.

This invention consists, rst, in arranging a cooler in combination withan air tight hinged case surrounding the same in such a manner that itcan be brought in a horizontal position when used for cooling and in avertical position when used for draining; second, in arranging thecooler withl double walls, the inner stationary walls to consist ofperforated sheet metal, and the outer movable walls to be arranged so asto form an air-tight inclosure around the perforated inner wall as longas the liquid is subjected to the cooling process, and which can readilybe removed if the draining operation is to commence; third, in combiningwith the cooler a perforated conical central tube for the purpose offacilitating the draining operation. y

To enable those skilled in the art to make and use my invention, l willproceed to' describe it with reference to the drawings.

A represents a frame, constructed of timber and of sufficient strengthfor the operation. Supported byA this frame and hinged to its bottomtimbers, c, is the case B, constructed of planks and fitted together soas to form an air-tight inclosure around the cooler. One side, b, ofsaid case is secured to the rest by means of clamps c, and india-rubberstrips d are employed to make the joints between this v side and theedges of the case tight. This of said'inclosure being kept in place bywedges g, interposed between the inside of the case B and the outside ofsaid walls, as clearly shown in Fig. 2. A conical perforated tube, D,veX- tends through the entire length of the cooler, andas long as theapparatus is in a horizontal position, as shown in Fig. 1 in red and inFig. 2 in black outlines, the interior of this tube is stopped up by aplug, h, to prevent the liquid sugar running through the perforations ofsaid tube. The tube terminates in a cistern, E, which is separated fromthe cooler by a partition, fi, and which occupies that portion of thecase B which is situated under the cooler if the apparatus is brought ina vertical position, as shown in Fig. l. As long as the apparatus isused for cooling, the ends of the tube D are stopped up. Thecistern Eserves to receive the molasses, and it is provided with a faucet, F,that serves to draw off its contents. The hot liquid sugar is introducedinto the cooler from the open kettles in which the juice is boiled, andafter it has granulated the apparatus is raised to a vertical position.To facilitate the operation of raising the apparatus, a bar, G, ishinged to the top edge of the' case B, and a rope, j,

is secured to this bar and drawn over a pul-` ley, k, which is suspendedfrom one of the top bars of the frame A. After the case B has beenraised to a vertical position by the aid of the ropej, the inclosure f,which surrounds the cooler,is re1noved,and the perforated walls of thecooler are strengthened by supporters Zand screws m., as clearly shownin Fig. 3. The plug h is now withdrawn from the inside of the tube D,and its ends are opened and the apparatus is ready for draining. Theoperation of draining is facilitated by introducing steam into the spacesurrounding the cooler C and by rarifying the air in the reservoir E.The molasses is forced toward the center, and it passes off through theperforations of the tube D, and it collects in the cistern E, fromwhence it is drawn olf by the aid of the faucet F. By these means thesugar is cooled and drained without removing it from the cooler C, andby the aid of the perforated conical tube D and the perforated walls e aperfect separation of the molasses from the granulated sugar iseffected, and it will be noticed that by the action of the pressure ofthe steam on the outside of the perforated sides of the cooler and bythe vacu um created under the conical tubes D all the molasses is drivento the center and collected in the reservoirE in a short and easymanner, and at the same time by the action of the steam the sugarcontained in the cooler C is bleached. A superior article is therebyproduced, and less labor is required than With other apparatuses for thesaine purJ pose.

Having thus described my invention, What l claim as new, and desire tosecure by Letters Patent, is-

1. The combination of a cooler, C, with an air-tight hinged case, B,constructed and operating substantially in the manner and for thepurpose specified.
